The 'purpose of this invention is to provide means for avoiding the wastage of the circulatory cooling medium of an internal com'- bustion engine which ordinarily 'occurs by' evaporation and escapes in the form of vapor from the radiator-.upon overheating. It consists in the elements and features of construction shown and described as indicated in the claims. v

In the drawings: Figure 1 is a vertical `section of a condenser embodying this invention indicated as mounted at the overflow connection ,of the j radiator of an automobile enginemshowing theiexpansible and reducible cham condenser fully e anded.

Fi re 2 is a slmilar view showing said cham r in collapsed condition.

The structure shown in the drawin comprises an expansible and reducible c amber which, as illustrated, is in'theform of a bellows, A, preferably-constructed as to its collapsible wall, of elastically stretclable material such as sheet rubber, fixed head, B, which in the form shown is t bottom ofv the chamber, and a movable head, C, which in the form Shown is the top of. the chamber,this bellows having its cavlty connected by means of a nipple, b, which terminates the bottom head B, for connection with the overflow nipple,

r of the served. The movable head is weighted'as respect"to weight. .It will be understood4 the vthickness shown, a hard indicated b d of moderate hickness `or a wood boar metal plate of .the-thickness indicated b the drawing, serving this purpose adequate y in that normally t e bellows is collapsed by the weight of themovable head as shown in Fig- 'elatory and weten-which w'l be retained inthe 5 I vapor in `the radiator developm ure 2, and that upon .thev generation of sure, vapor will pass into the b ows ambe'r causing itto be expanded, lifting the movable head, and that t is ex 'ansion to the extent of the capacity ofthe llows at its most expanded condition 'will accommodate the va or generated by heating the circuuid, customaril a mixture of alcohol expanded bellows and there condensed by jreason of the exposure of the chamber to exterior-'atmospheric temperature conditions, the liquid of condensation owingback into the liquid 4of pressure.

and comprisina` ofl thelradiator to be `d some resi the radiatonso that a bellows of limited s1ze wlll'take throughout avconsiderably long condition of overheatlng ofthe engine, because of the constant re-condensation and return flow of into theradiator. against extreme overheating andi vaporization of the circulato 1s provided through t ofthe bellows, normalli F, whic may be adjusted permit the valve to ope pressure m the bellowsat any desired stage Preferably the entire bellows constitutmg the expansible and reducible flziamber tlencled inha protective casin ,moun ri wit respect to the fixed head B, of thegbellbws. mg ispreferably provided wit apertures as shown at h, h, for ventilation to facilitate the radiation from the expansible and reducible chamber the condensation I claim:-

1. A device for the pu prlsing-an expansible an reducible chamber adapted for communication' with a source of vapor to be condensed, said chamber being normally reduced and adapted'to ex and uner the pressure of the vapor devel the vapor source and disc chamber, said chamber being exteriorly exposed to atmospheric cooling for condensing the vapor and permittingreduction of the chamber.

2. In the construction defined in claim 1,

controlled bye valve, D1, held by a screw, G, to
